Spider rappelling! A great way to get around.

When a spider wants to make a long distance traverse between two objects, or just wants a quick way to ascend an obstacle, what can he do? Lets find out by watching a male crab spider.

Well, as in ballooning, the spider can jet out a thread of silk, letting it be carried by the wind.

The spider then turns and checks the tension on the web to see if it has snagged a target. In this case, there is no tension, so the spider reels in the thread. I am not sure if crab spiders consume the spent silk.

Another try, in another direction.

This time the tension is right, and the spider quickly disappears from the frame.
